In a revealing new interview on tonight’s “Late Show with David Letterman,” Jessica Simpson tackles questions about her weight, her highly publicized split from NFL star Tony Romo, and John Mayer’s headline-grabbing interview in which he talked about his sex life with the singer.

“Unfortunately, people were talking about my weight for a year,” Jessica told Dave, adding, “Yeah, that’s the fat woman in Hollywood, apparently.” She went on to say, “Hey, it was fine to me … I was confident. I wouldn’t have been on stage if I wasn’t confident.”

And Jessica’s reaction to the photo fallout? “Well, normally you would think that I’d become anorexic after what everybody was saying about me,” she said, “but I just decided to eat more … Why not? Enjoy life.”
The blonde beauty also opened up about ex-boyfriend John Mayer’s interview, in which he referred to Jessica as “sexual napalm,” saying, “he gave away my game.”

“Yeah, I mean, normally you would think that somebody you care about would keep those intimate details to himself…,” she went on to say. “I mean, it was definitely a compliment, in a way, but I don’t really want people to know that about me. That’s, you know, I’m like the good girl and then that happens.”

When asked about her ex-boyfriend Tony Romo, Jessica said the two have remained friends, adding, “I still look at his cute butt in the [football] outfit … He’s a good guy.” She also mentioned that he broke up with her on her birthday, but that she thinks that the they will remain friends for life.

The singer is opening up to Playboy magazine about his many conquests, particularly Jessica Simpson, whom he likens to crack cocaine.

“Drugs aren’t good for you if you do lots of them,” he says in the mag’s March issue. “Yeah, that girl is like crack cocaine to me.”

Simpson dyed her blonde hair dark brown and tried to become intellectual during her on and off relationship with Mayer in 2007. She also famously retained her virginity until her marriage to Nick Lachey, which ended in 2005.

But Mayer does his best to dismantle Simpson’s good girl image by describing his sexual relationship with her as “crazy,” calling it “sexual napalm.”

Simpson’s response? She tweeted Wednesday: “interesting day so far…hmm” before making a reference to boxing.

He’s also under fire for comments he made in the same article about African-American women.

Jessica Simpson is bouncing back - and in style.

She revealed more curves in a sequined mini as younger sister Ashlee made her Broadway debut Monday night in Chicago.

Simpson, 29, has endured a rough 2009: she was blasted for her weight, lost her beloved dog Daisy to a coyote and was dumped the day before her 29th birthday by Dallas Cowboys quarterback Tony Romo.

Martha Stewart, who’s known for running her mouth, is now apologizing to Jessica Simpson after mildly blaming her for the abduction of malti-poo dog Daisy!

At Us Weekly’s 25 Most Stylish New Yorkers party on Sept. 15, Stewart threw a dig at Simpson calling the incident “pretty sad” and saying that she “should have been more careful” and also recommend that the singer “get another dog” in order to ease the pain.

Fortunately, Martha has since realized her comments to Jess were a tad harsh.

“I said that she should have been watching her dog more closely, but I feel very, very sorry for anybody that loses a pet,” she said on The Martha Stewart Show Thursday. “Jessica, I hope you find your pet, but if you don’t, I’m really sorry that you lost one.”

The singer tweeted on Monday night that she watched her dog, Daisy, get snatched by a coyote.

“My heart is broken because a coyote took my precious Daisy right in front of our eyes. HORROR! We are searching. Hoping. Please help!”

Simpson’s heart had previously been broken by Tony Romo, who dumped her on the eve of her 29th birthday in July.

Daisy was a gift to Simpson from her ex-husband, Nick Lachey, who surprised her with the puppy onstage during a concert. She rarely travels without the 5-year-old dog, who rides in style in Louis Vuitton dog carriers.

Simpson and her family are offering a reward for information on the dog’s whereabouts.
